Reduce size of installed CLI

### Describe the feature

The bulk of the CLI is uncompressed data from botocore. Per https://github.com/boto/botocore/issues/3485#issuecomment-3726250475, it seems that more recent botocore implementations compress this data. It would be nice for the SDK to also compress this data. It's not clear to me why there's a botocore fork either, but that's not really my concern.

### Use Case

The AWS CLI tends to be installed lots of places, including in docker images where it will tend to be copied/downloaded repeatedly. Having it be significantly smaller would result in cost savings for those who use it.

### Proposed Solution

Consider using botocore's compressed implementation or another compression solution.

### Other Information

Comparison of the expanded data vs zip compression:
```
% zip -9 -r -p -q data.zip data
% du -h -s data.zip data
12M /tmp/data.zip
103M data
%
```
